Specification of Letters Patent.

Patented May 28,1912.

Application filed April 12, 1911. Serial No. 620,590.

To all whom it may concern Be it known that 1, JOHN H. Gonnrsrnn, acitizen of the United States, residing at Cleveland, in the county ofCuyahoga and State of Ohio, have invented a certain new and usefulImprovement in Combined Adjustable Pliers and Wrenches, of which thefollowing is a full, clear, and exact description.

This inventionrelates to a combined'plier and wrench, or a tool whichmay be used in either of" these capacities. Its object is to connect thetwo members, each of which includes the usual jaw and handle, upon apivot in such manner that the distance be: tween the jaws may be variedwithin a wide range; and at all points of adjustment the jaws, whenclosed,'are substantially parallel to each other on their working faces.

A further object is to so construct and arrange the several parts of thetool that the said adjustments of the jaws may be quickly and easilyeffected, without thenecessity for loosening any special pivotfastenings or the manipulationof any pivot locking devices.

A further, object is to produce a plierwrench'in which the jaws, at anypoint of separation, may not be closed beyond the point of parallelismand to provide means, if desired, for holding them securely in suchposition.

A further object is to produce a tool of the'character described'whichshall be simple in construction, cheap to make and easy tomanipulate,these and other objects being carried out in'a satisfactorymanner by that embodiment of the invention shown in the accompanyingdrawings. This showing, however, is that of the now preferred forms ofdetails and assemblage of the parts which may be varied, doubtless, incertain respects without material departure from the spirit of theinvention, as set forthin the claims at the end of this specification.

In the drawings, Figure l is a side elevation of the preferred form ofwrench-andplier with the members so set upon the pivot that the jaws arein their most widely separated or distant positions. Fig. 2 is a similarview, showing the pivot adjusted to a position where the jaws arebroughtinto their closest closed relation',the dotted lines in both of thesefigures indicating the positions of one'of the jaws relatively to theother when swung open. Fig. 3 is a perspective yiew of one of the jawheads detached. Fig.

comprises a jaw A, a handle A below it,

and between them a side lug or extension A upon which the pivot ispermanently secured. The member B comprises a similar jaw B and handle Bwith lug extension B in which a rectangular slot Z) is formedsubst-antially at a righfiangle to the plane of the jaw face, andprovided with ratchet teeth 6 along its upper edge.

The pivot in the construction shown consists of a bolt having anenlarged flat head a and a square shank a which extends through both ofthe main members of the tool and terminates at its end in a reducedscrew threaded portion a This squared shank is adapted to fit snugly ina corresponding opening a in the jaw A, and upon it is mounted a ratchetlug C provided with a square aperture which fits over the squared bodyof the bolt to hold it from turning. Upon the round screw threadedportion of the bolt is mounted a spacing thimble d and a washer ofconsiderable size to partly cover the aperture 7) in the opposed memberB of the tool. A nut a on the end of the bolt clampsthe parts securelytogether, the

member B lying between the washer and op posed member A. The aperture 6in the member B is preferably rectangular and provided on its upper edgewith a series of serrations or ratchet teeth 6. The lugC is provided onits upper side with a series of ratchet teeth 0 adapted to engage theteeth of the member B,-and, when in operative position, the lug is ofsufficient depth to completely fill the aperture from top to bot- I tomand prevent the ratchet teeth.

The lower flat face 0 oft-he lug bears against the lower sideof the slotwhen the ratchet teeth are-engaged and the jaws in parallelism. Onelower corner 0 and the diagonally opposite upper corner 0 of the lug arebeveled or cut away in order to afford space for swinging the slottedmember B to a position where the ratchet teeth disengagement of the ofsaid member may be disengaged from those of the pivot lug and space isprovided to free the lug andpermit of its being moved along in the slotto some new position of adjustment. It is preferred that the lowercut-away corner 0 be curved concentrically about the axis of the pivot.The lower fiat portion 0 of the lug lies on the opposite side from thejaw face A of a longitudinal line through the pivot axis, and it bearsagainst the lower side of the slot stopping the closing movement of themembers at that stage where the jaws arrive at parallelism andpreventing further movement in this direction. Means may be employed, ifdesired, to lock the main members in this position, that is to preventthem from opening, and thus better fit the implement for use as awrench. Any desired means to this end may be employed; as for example, asimple rectangular loop E, Fig. 6, adapted to be raised to a contractedpoint on the handles close under the side extensions A and B to releasethe handles, and then, after the jaws are adjusted, to be slipped downover the expanding part of the handles to hold them in closed relationwith the flat port-ion 0 of the lug bearing against the bottom edge ofthe slot.

By these means the pivot point may be shifted to any position along theaperture 7) that will give the desired opening be tween the jaws, and itwill be noted that when these jaws are closed in any of these positionstheir working faces are substantially parallel with each other, so thatthey may properly grip without injury any article between them; or, ifused as a wrench,

they will. grip flatly upon the sides of the nut without injury to itscorners.

Each of the jaws A and B have faces A and B as Wide as the combinedthickness of both handles, the jaws being offset as at a and Z) toeffect this purpose.

The ratchet lug C may, if desired, be made integral with the member A,and therefore be independent of the pivot bolt shank a, for compellingit to turn with said member. In such event, the main shank a, of thebolt may be round instead of square, but it must be larger than thethreaded end a in order to form a shoulder against which the spacingthimble (Z will bear.

The construction above described affords an instrument in which thespace between the jaws may be quickly changed without in any wayaffecting the parallelism of the jaws when they are closed to operativeposit-ion.

Having thus described the invention what is claimed as new and usefulis:

1. In a combined plier and wrench comprising two pivotally connectedmembers each having a jaw and a handle on opposite sides of the pivot,the combination of said members with overlapping side extensions oneach, a rectangular slot in the side extension of one member withratchet teeth formed along' one of its long sides, a pivot lug on theother member having at one side a series of teeth adapted to engagethose in one side of said slot while the opposite flat side of the lugbears against the opposite side of the slot, whereby the ratchet teethof the lug and slot are held in engagement, with two diagonally oppositecorners of the lug cut away to permit of the disengagement of saidratchet teeth and freeing the lug.

2. In a combined plier and wrench comprising two pivotally connectedmembers each having a jaw and a handle on opposite sides of the pivot,the combination of said members with overlapping side extensions oneach, a rectangular slot in the side extension of one member withratchet teeth formed along one of its long sides, a pivot lug on theother member having at one side a series of teeth adapted to engagethose in one side of said slot while the opposite flat side of the lugbears against the opposite side of the slot, whereby the ratchet teethof the lug and slot are held in engagement, with two diagonally oppositecorners of the lug cut away to permit of the disengagement of saidratchet teeth and freeing the lug, said slot lying at substantially aright angle to the length of the member and to the working face of itsjaw, whereby the jaws of both members are parallel when closed in anyposition of pivotal adjustment along the slot.

3. In a combined plier and wrench comprising two pivotally connectedmembers each having a jaw and a handle on opposite sides of the pivot,the combination of said members with overlapping side extensions oneach, a rectangular slot in the side extension of one member withratchet teeth formed along one of its long sides, a pivot lug on theother member having at one side a series of teeth adapted to engagethose in one side of said slot while the opposite flat side of the lugbears against the opposite side of the slot, whereby the ratchet teethof the lug and slot are held in engagement, with two diagonally oppositecorners of the lug cut away to permit of the disengagement of saidratchet teeth and freeing the lug, said slot lying at substantially aright angle to the length of the member and to the working face of itsaw, that portion of the lug which bears upon the lower edge of the slotbeing upon the opposite side of the pivot axis from the jaw of itsmember, whereby it stops further closing movement of the jaws when theyarrive at parallelism.

4C. In a combined plier and wrench comprising two pivotally connectedmembers each having a jaw and a handle on opposite sideslof the pivot,the combination of said members one of which has a slot which liessubstantially at a right angle to the length of the member and isprovided at one side with a series of ratchet teeth, the other memherhaving a rigid lug which is provided with ratchet teeth to enage thoseof the slot and is adapted, when the jaws are closed, to engage bothsides of the slot, cutaway corners on the lag to permit the members toswing to open the jaws, with means which stop the closing movements ofthe members when the jaws arrive at parallelism.

5. In a combined plier and wrench, the combination of two pivotallyconnected members each having a jaw and a handle on opposite sides ofthe pivot, a slot in one to the length of the member and provided withratchet teeth alongone edge, a rigid pivot lug on the other memberadapted to lie in and be adjusted along said slot, ratchet teeth on saidlug to engage those of the slot, means to prevent the jaws from beingclosed past positions where their working faces are parallel, and meansto lock the members against opening movements in any position ofadjustment.

In testimony whereof, I hereunto aflix my signature in the presence oftwo witnesses.
